First, mix some really fresh fuel...Ryobi recommends a mixture of 50;1 or 2.6 oz of oil to 1 gal of gas. empty your tank and while it is empty check the fuel cap on the tank to make sure the vent in the cap is not clogged, if it is it will cause a vacuum to be created in the tank and it will not allow fuel to go to the carb. Check the filter on the intake hose inside the tank to be sure it is not clogged ( I replace this filter once a year whether it needs it or not...just a good maintenance practice, they're cheap and I buy them three or four at a time...available at any small engine shop) check fuel lines and be sure they are open.( I disconnect both lines from the carb and blow a little compressed air through them, be sure you reconnect them correctly or do them one at a time). Refill tank with the FRESH gas...Try to start your machine....prime the bulb 7 or 8 times and place choke in start position...pull start handle at least 6 times... if the machine doesn't start...pull out the plug and see if you are getting fuel to the cylinder...if plug is wet you are getting fuel...if it is dry or gummy you are not getting fuel (i'll talk about this later)...then clean plug and plug it back into the plug wire...lay plug against cylinder head and pull start handle to see if you are getting spark...it should show a blue spark at the electrode of the plug...if you have spark you know that the magneto is good...if not you have a problem in the electrical circuit...OK, assuming you have spark and fuel...you may have too much or too little fuel....turn low speed mixture needle ( the one on the left nearest the engine) in clockwise gently till it stops then back it out counterclockwise 1 to 1 1/4 turns. This should allow the engine to start...when it starts adjust screw in or out in 1/8 turn increments until you acheive a smooth idle...then throttle up and see if it will go to full throttle...you may have to adjust the high speed needle a bit to get a smooth transition from idle to full throttle...once you find this "sweet spot " turn the H needle 1/8 turn counterclockwise to allow it to run just a bit rich at full throttle. remenber when adjusting these needles...counterclockwise = more fuel...clockwise = less fuel !!! other things to check are, tightness of screws on carburetor, check the four screws on the back of the rear crankcase plate ( the rear part of the case that holds the gas tank on...the four screws above the gas tank) to make sure they are tight as any air leaks in either will make your machine a ***** to run or tune, there is a gasket under these plastic parts which can get warped by the heat of the engine allowing air leaks..check fuel lines for cracks sometimes they will get gummy soft, crack, and decompose....Now, as I stated earlier, if you are not getting fuel to the cylinder more than likely you have a clogged or gummed up carburetor and this will necessitate either a good cleaning or a rebuild...either is easy to do....if this is the case, google "Zama carbs" and click on Zama technical manual this downloadable manual will tell you all you need to know about cleaning or rebuilding your carb....Hope this gets you going...;-D

I have a Ryobi RY28120 gas powered weedeater that will start sometimes and not at others. Not sure if the carb needs cleaning or if it need a new muffler. Maybe adjusting carb screws? Not sure! Also,...


Use only fresh gasoline (alcohol free if you can find it). Purchase a top quality synthetic 2 stroke oil such as Lucas, Golden Spectra and mix it exactly as the manufacture dictates. Install a new accurately gapped plug and make sure the plug wire cap (boot) is pulled back to inspect the wire to connector crimp. Start it up as you normally would to allow the new gas and oil to permiate the system and if you cannot get it to stay running without the choke being on shut it down and squirt some oil into the carburetor and pull the trimmer over, if this makes it start everytime it does not want to start and it allows you to click off of run you have either low compression (rings are worn). or your carb is yet another victim of the geniouses that thought alcohol in gas was a super idea. Either way you can replace the piston and rings or the carb. both are almost not worth the time and cost anymore, a new carb for mine is $70.00, with a new piston and ring set being around $40.00 and a brand new trimmer the same as this one on sale at $130.00 it was an easy decision to buy new.

Pollan weedeater


That unit probably has a high side and a low side screw in the carb. Maybe, the screws are out of adjustment. One should have the letter L along side of it, that's the low side or idle side. The other of course would be the letter H which is the high side. That adjustment is only to be made when the unit is started and idling. When you give it full throttle that's when you adjust the H screw. Factory settings are usually 1 1/4 turns out from dead stop on the L screw and approx 3/4 to 1 turn on the H screw after unit is running. If however, this doesn't solve the problem a simple carb kit can be purchased for about 5 bucks and very easy to install. Good luck.

Ryobi BC30 Weedeater - Cannot Start


Check the fuel lines for cracks/breaks. If they are o.k., then:

You will need to disassemble the carburetor and spray with carb.cleaner. Make sure the small screen is free of debris. (Should be able to see daylight through it.) Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152), to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If you need further assistance, just let me know.

Blowing gas out the air intake


Eight years is great for a weedeater! Blowing out can mean something is stuck in the reed valves, or one may be broken. They are just under the carb, usually. Be real careful with the gaskets. If you mess up any, silicone will do. Use good car gasket silicone.
